ORE-SEPARATOR.

SPECIFICATION forming; part of Letters PatentNo. 664,635, dated December25, 1900.

Application led April 19, 1900.

To all whom, it #tay concern:

Beit known that I, AeUsTUs CARL HAR- TUNG, a citizenof the UnitedStates, residing at Galena, in the con nty of Cherokee and State ofKansas, have made certain new and 'useful Improvements inOre-Separators,of which the following is a specification.

It is the object of my invention to provide an improved apparatus forseparating ores from sand and dirt, the same being particularly adaptedfor the treatment of lead and zinc ores.

The construction, arrangement, and operation of parts are as hereinafterdescribed, reference being had to the accompanying drawings, in which-Figure l is a perspective view of my improved apparatus. Fig. 2 is aplan view of a roller bearing and gearing. Fig. 3 is a verticaltransverse section of the apparatus. Fig. 4 is a vertical section on theline 4 4c of Fig. 3.

The working parts of the apparatus are arranged within and supported bya frame A, composed of two four-square or rectangular portions arrangedvertically at right angles to each other. A vertical shaft B is arrangedand fixed at the intersection of the frames A. Around this shaft Bcertain parts of the apparatus are adapted to rotate, while others` arexed thereon. As shown in Fig. 3, a circular base-plate C is tiXed on thebase of the frames A. Upon this base-plate C is arranged aroller-support D for the table E, upon which the material to be treatedis deposited. The said support combines rollers d and a toothgear d',exterior to the rollers, as shown in Fig. 2. The said tooth-gear dmeshes in practice with a driving-gear (not shown) and is thereforedriven at any required rate of speed. The rollers d are journaled onaxes arranged radially in the support D and are journaled on thebase-support C. The table E rests on the rollers d and is caused torotate around the shaft B by means of friction with said rollers. Thistable E is provided with a surrounding metal rim F, which may beadjusted higher or lower, as required, to maintain a certain depth ofsludge or slime on the table. The means for thus adjusting it are screwsG,which work through ears f, attached to the rim F, and also throughears e, attached Serial No. 13,561. (No model.)

ranged vertically and atashort distance from i itsedge, as shown in Fig.3, for the purpose of preventing the material from passing o the disk orspreaderI, so as to strike on the table too far from the center. Themingled sand or ore, gangue, and water are thus delivered upon the tableand spread out thereon, so that the heavier material remains nearest thecenter, while the lighter is disseminated nearer the periphery. In orderto pack the material and spread it more evenly upon.

the table E, I employ canvas sweeps J, (see Fig. 1,) the same consistingof canvas attached to rods j, which project laterally from the spreaderI. These sweeps occupy about onehalf the width of the table E. They maybe provided with transverse battens and weighted, if desired, to morethoroughly accomplish the object.

K indicates a scraper or plow which is right angular in cross-sectionandv constructed of boiler-plate or some other material. It is slightlycurved lengthwise, and its horizontal llange is out out at the front endto better adapt it to take up material on the table E. The outer. end ofthe, scraper or plow K eX- tends beyond the rim F of the table, so thatthe material taken up by it may be conveyed upward and delivered in anysuitable receptacle provided for the purpose. The scraper is attached toa vertical bar or standard L and to a diagonal brace M, which is alsoattached to the head of the standard. The latter slides verticallythrough a bearing-block N and may be adjusted higher or lower by meansof a hand-lever O, which is pivoted by a link n to the bearing N. Forthe purpose of holding the said lever in any position into which it maybe adjusted, and thereby locking the scraper at any desired elevation, Iemploy the hook P, which is pivoted to said IOO lever and whose lowerend is adapted to enter one of a series ot' holes provided in a guidebarp, forming an attachment of the bar N. The latter is adapted to slidetoward and from the post B upon a horizontal bar Q. The means foradjusting the bearing, and thereby the scraper K, toward the shaft is ahand-lever R, which is pivoted to the said bearing N and provided with ahinged pawl 1', which engages ratchet-teeth on the bar Q. By vibratingthe lever R in a vertical plane the bearing N and scraper K may beadjusted toward the shaft B, since the pawl r will automatically take anew hold on the ratchet at each vibration. This lever is requisite,since it requires considerable pressure to t'orce the plow or scraper Kinward against the pressure of the slime or solid material on the tableE. For adjusting the bearing N and scraper K outward no mechanicaldevice is required, since there is no pressure to be overcome, butsimply the friction of the bar Q. The object of thus adjusting thescraper K farther inward or nearer the periphery of the table E is totake up and deliver from the table different grades of the materialthereonthat is to say, the heavier material will be deposited nearer thecenter and the lighter will lie nearer the edge of the table--and by theadjustment of the scraper K higher or lower or nearer to or farther fromthe shaft B any desired quantity or grade ot' material may be removedand deposited in separate receptacles provided for the purpose. It willbe understood that this material is taken up by the l plow inyconsequence of the rotation of the table as it travels on therollersupport D. To adapt the scraper to thus deliver into dii-terentreceptacles, I provide for adjustment of the same in a circle'concentricwith the shaft B-that is to say, the ratchet-bar Q is adapted to swinghorizontally on the shaft B and its outer end is supported upon an arcbar S, which is arranged horizontally concentric with the table andsecured at its ends to two adjacent vertical supports ot the frame A.The under side of said bar S is provided with notches, and a dog orlocking-lever T is pivoted in a slot in the end of the bar Q and adaptedto engage the said notches, as shown in Fig. l. By this means the bar Qand its attachments, particularly the scraper K, may ,be located in anyadjustment around shaft B.

The horizontal angle or inclination of the scraper K may be also Vvariedat will, so as to scraper and passes through a keeper on the Y brace M.A segmental rack-bar Vis attached to the bearing N and arrangedconcentrically with the standard L. The inner side of this segment isnotched to receive the lever V, by

which construction it is apparent that the Y plow may be locked in anytangential adjnst-V n ment required.

Having thus fully described my invention, I what I claim as new, anddesire to secure byV Letters Patent, is-

l. The combination, with a table adapted to rotate as described, of aplow or scraper, Y'

a bar arranged radially over thetable, means for suspending the scraperfrom said bar, and

a lever and pawl, thelatter being adapted to engage teeth on the barwhereby the scraper may be forced inward, as shown and de-l Y scribed. Y

2. The combination, with a rotating table, Y

and a scraper adapted to work thereon, of' a bar arranged radially abovesaid table andV adapted to be adjusted laterally, a notched L Y arc bararranged concentrically with the ta-V Y ble and eXteriorly thereto, anda dog for locking the radial bar to such arc bar, substan- Y tially asshown and described.

3. The combination, with the rotating table, of a scraper arranged towork on the surface of said table, a vertical' rotatable stand- 1 Y ardto which the scraper is rigidly attached,

a lever pivoted to the scraper, a curved rack-Y Y; Y

bar wherewith said *lever engages, a guide for Y the standard andsupport for said rack-bar,

device for locking said lever in any adjustment, substantially as shownand described- AGUSTUS C. HARTUNG.
